1. Mujo no oto. Japanese for ‘the sound of impermanence’. Mujo or impermanence is an important concept in Buddhism and central to Zen aesthetics. This phrase also references Basho’s original haiku, the final line of which is ‘mizu no oto‘ – the sound of water.

2. Gero gero is the Japanese onomatopoeia for a frog’s croak, but is also used adverbially to describe vomiting. This pun was one of the inspirations for the poem.

I cobbled together this longer poem from some ideas generated as I created the first Basho poem, After the frog. In this one, I imagine Basho retiring to a solitary hermitage (in a shady glade, with lacy moths, pools, etc.) and himself diving into a pool to join the frogs. The ‘gero‘ grows more urgent inside him until he can’t contain it (‘a faster gero note’). He vomits salt, and sees that he himself has become a frog.

The final stanza is itself a haiku, and nicely captures the essence of the poem: all regret and suffering disappears in this hermit’s final resting place.
